[support] A beginner's questions

[Kovács István]

Hi,

I'd like to set up a VPS hosting two sites (in two different domains),
on top of Ubuntu (Debian) Linux. I'd like to know the following:
- how do I configure the two sites, sharing a single Drupal
installation, to use different configuration and databases? My web
server is Apache;
- is it possible to theme different parts of the same site
differently? E.g. my wife would probably prefer different colours for
her blog than I would for mine :-)

TIA,
Kofa
